Rebar measurement like never before

up to three strands in one measuring gauge • Provides 100 per cent inspection in real time • Reduces start-up time • Increases the repeatability and precision of end product • Improves process control • Reduces scrap and production costs • Saves raw material and post- processing costs • Detects process problems at an early stage •

Industry 4.0 ready – OPC UA (integrates in a seamless way to the users’ network or higher-level systems) • Simple cleaning requirements, giving short maintenance needs • Logging of all production data for QC • Makes post-production measurements irrelevant • Reliable operation in harsh conditions, product temperatures up to 1,200°C Zumbach Electronic AG – Switzerland Website : www.zumbach.com

ZUMBACH Electronic, a supplier of non-contact measuring technologies for the metal and steel industry, has introduced its newest Profilemaster SPS 80 gauge for in-line measurement of any rebar type. Sophisticated capabilities allow the measurement of rebar products in hot rolling processes. With a unique processing feature, the full contour of a rebar is captured and the cross section is extracted in such a way that core diameter, rib height, width and height, among other characteristics, can be measured and monitored. The Profilemaster SPS 80 is designed to measure the rebar in the rolling mill without having limitations in terms of rolling speed. Since many rolling mills produce rebar in more than one strand, Profilemaster can handle up to three strands simultaneously with a single gauge. Every individual strand is measured and related statistics can be generated. Zumbach’s experience of supplying measuring systems into the metal and steel market helped it design a solid and reliable system for such applications and will help its customers produce rebar products with higher quality and efficiency. The Profilemaster family consists of various models and, depending on the product size, Zumbach offers the most suitable model that will accommodate the complete range of products. Profilemaster systems are available with four to eight laser/camera modules continuously measuring the cross section of the moving product. A powerful PC-based processor combines the captured line images of the individual cameras to yield the momentary cross-section of the profile. All relevant dimensions such as width, height, angle and radius or other geometric quantities are computed to characterise the full cross-sectional picture. An operator-friendly graphic display of this data allows the monitoring of the product during the whole process. The nominal values for the profile can be directly imported from CAD design files, which allows easy and problem-free configuration of the device.

Customer benefits/main features are:

• Rebar measurement irrelevant to rolling speed • Multi-strand measurement of rebar
